in measuring the volume of cylinders, which dimension should you be more accurate about? the length or the diameter?..explain why.

the radius (or the diameter) because the radius is squared when you calculate the volume, so any inaccuracies will be amplified.

because the area of the cross section is a square function of the diameter, which means error is compounded. In fact, the same percentage error in measuring the diameter will have approximately twice the impact on the accuracy of the overall figure as length.

The diameter.
The volume of a cylinder is (d/2)²πh. An error to the diameter is increased by squaring it.
